I have some parquet files (https://github.com/hangxie/parquet-tools/tree/main/cmd/testdata) created by my tool written in go, some of them are not readable by this extension, would you please use them as test cases? Their corresponding JSON/JSONL dump can be found under golden/, they are not exactly the same as Java or Python parquet-tools output though I tried my best.
So far the problem is DECIMAL, you can try it with reinterpret-scalar.parquet which is a flat table, once this works I'd like to see this extension supports all-types.parquet which has quite some data types and complicated structures.
I don't know enough (anything?) about TypeScript, but I can help if you have any questions about the test data or want to generate some more test cases.
